Development environment and tools

Let's look at the development environment and the tools that we will need to create and run the serverless applications that we will create in later chapters. We will be using Visual Studio Code for code editing, Node.js and JavaScript for writing our serverless applications, and we will use tools such as Postman to test our serverless applications. Let's start by looking at what Visual Studio Code is, the benefits it provides, its installation instructions, and the Visual Studio Code user interface.
